Measuring 36.6mm in diameter and 12.05mm thick, this Ballon Bleu de Cartier is crafted entirely in 18k yellow gold, from its rounded case to its matching bracelet. The fluted crown is set with a blue cabochon-shaped sapphire, a hallmark detail that lends the watch its distinctive character.
The silvered guilloché lacquered opaline dial is dressed with Roman numerals and blued-steel sword-shaped hands, framed beneath a sapphire crystal. A self-winding mechanical movement powers the watch, which carries a water resistance rating of 3 bar, approximately 30 meters or 100 feet.
Reference WGBB0011 is a study in proportion and material harmony, pairing warm yellow gold throughout with carefully chosen details that remain consistent with Cartier's design language. As with all Cartier creations, subtle variations in precious stone carat weight and number may exist between individual pieces.
